Second jobs and multiple income sources
Plenty of households now run more than one income stream: a primary job plus a second role, a salary plus a side business, or several part-time positions that add up to more than one full-time wage. Lenders assess each source separately rather than adding them up, and the rules for a second job are not the rules for the first.
How a second job is assessed
Most lenders want to see a history in the second role, commonly six to twelve months, before counting the income at all, and some require longer. The reasoning is that a second job is the first thing to go when life gets busy, so lenders look for evidence it is sustained rather than recent. Where the history exists, the income is often counted at a similar rate to your primary employment; where it does not, it may be excluded entirely, which can be the whole difference on a tight file.
Where the sources are different in kind
A salary plus rental income, a salary plus a small business, or a salary plus investment income are each assessed under their own rules rather than blended. Rental income is discounted for vacancy and costs. Business income brings self-employed assessment into play even where it is modest. The practical effect is that two households with identical total income can be assessed very differently depending on where the money comes from.
Part-time roles that add up
Several part-time positions can be assessed close to a full-time equivalent where the pattern is stable and evidenced, particularly within the same industry. What lenders look for is consistency across the roles and continuity over time, rather than a snapshot of a single busy month. Two years of payslips across the roles does more for this file than any explanation.
The honest caution
A borrowing figure built on a second job assumes you will keep working the second job for as long as the loan runs. That is a genuine commitment, and it is worth deciding deliberately rather than by default. If the second income is temporary, or exists to reach a particular purchase, the repayment should be one you could still meet if it stopped.
What lenders look for across multiple incomes
Four factors that decide how much of the total actually counts.
Commonly six to twelve months minimum, sometimes longer. Recent second jobs are frequently excluded entirely.
Salary, rental, business and investment income are each assessed under their own rules rather than added together.
Steady hours across two years reads very differently from a recent spike. Two years of payslips is the evidence that works.
The repayment should survive the second income stopping. That is a planning question as much as a lending one.
Several income sources and a bank that will only count one?

Multiple income questions
Will a lender count my second job?
Usually only once there is a track record, commonly six to twelve months and sometimes longer, and the requirement differs between lenders. Where the history exists the income is frequently counted at a rate similar to your main employment. Where the second job is recent, many lenders will exclude it entirely, which is often the difference on a file that is otherwise close.
Do several part-time jobs count as full-time?
They can be assessed close to it where the pattern is stable, evidenced and ideally within the same industry. What matters is consistency over time rather than the number of employers. Two years of payslips across the roles is the evidence that makes the case.
How is rental income from an existing property treated?
Discounted, typically to allow for vacancy and holding costs, with the discount rate varying by lender. It is genuine income and it counts, but it does not count at face value, and the discount is one of the settings that makes lenders differ so much on investor files.
I have a salary and a small side business. What happens?
The salary is assessed conventionally and the business brings self-employed assessment into play, which usually means tax returns and financials even where the business is small. Some lenders handle the combination comfortably; others make it harder than it needs to be. It is a placement question.
Should I take on a second job to increase my borrowing power?
Only if you intend to keep it. Lenders generally will not count it until there is history anyway, so it is not a quick fix, and a loan sized around an income you plan to stop is a position worth avoiding. There are usually faster levers. What actually works.
